The Lyon defence is standing firm, and if anything the Ospreys are going backwards at the moment.

Jack Walsh and Keelan Giles help the Ospreys up to half-way, before a loose pass moves them back 15 metres.

Two minutes left. Two points in it.

Dan Edwards' penalty gets Ospreys up to their own 10-metre line, and the line-out finds Kieran Williams.

Make or break stuff now.

Rhys Davies is helped off the field, clearly in some discomfort.

A disappointing end for him, but we have a grandstand four minutes ahead of us here.

Will it be Ospreys or Lyon who advance to the semi-finals?

Jac Morgan again! You are kidding me! How has he got his hands on that?!

That is an unbelievable turnover!

Penalty to Ospreys!

Jac Morgan is the man involved once again, and he has a shiner on his left eye to show for it.

Has he just kept his team in this game?

Into the final five minutes.

Lyon are a few metres out, right in front of the posts.

The on-field decision stands, a bouncing ball at the breakdown came off an Ospreys knee - not a Lyon hand.

A real chance now for the French side to move two scores ahead.

Or will it?

Referee Andrew Brace wants to take a look at something.

Lyon respond brilliantly, though, winning the ball back before putting an excellent kick in behind the Ospreys defence.

Dan Kasende has to track all the way back, but he is forced into his own in-goal area and it will be a five-metre scrum to Lyon.

You can sense the nerves from the Lyon players now, and so do the crowd in the Swansea.com Stadium.

Vincent Rattez makes a hash of receiving an Ospreys kick, and can only put it out for a line-out to the hosts in Lyon territory.

I thought the conversion had gone and almost sneaked over.

With eight minutes to go this is going to be really nervy.

Into the final 10 minutes in Swansea, and Ospreys are on the attack once more.

They have another line-out deep in Lyon territory, and the driving maul is moving!

Lyon do well at the scrum, but Baptiste Couilloud's kick goes out on the full and the Ospreys will have the line-out on the Lyon 10-metre line.

Lyon - literally - hand momentum back to Ospreys as the line-out goes straight to a blue shirt.

Unfortunately the Ospreys cannot take advantage, and replacement hooker George McGuigan drops a pass forward.

It will be a Lyon scrum a few metres inside their own half.

The game is still finely poised with 12 minutes to play.

The biggest Lyon cheer of the day comes as Mickael Guillard wins a penalty at the breakdown.

The replacement lock has made his mark on this second half.

Lyon win the ball back in their own 22 once more but the clearing kick does not find touch.

This is relentless pressure from Ospreys.

The Ospreys backs needed to step up there because physically Lyon have been up to it today.

Morgan Morse drives to dive over a pile of bodies, and it is the wrong option as he is held up.

Lyon will - for a moment at least - be able to get the ball out of their own 22.
